Major Plot Twists & Surprises

1. Adam’s Hidden Long-Standing Crush In the novel, it’s revealed late that Adam has been attracted to Olive since their very first awkward meeting years earlier. The movie includes the flashback but omits the long-hidden crush — he doesn’t reveal that he’s had feelings for Olive before the fake-dating arrangement.

2. Holden Rodriguez Removed Holden, a significant character in the book who is Adam’s friend and develops a romantic subplot with Malcolm, doesn’t appear in the movie. This cuts out some of the story’s emotional texture and subplots.

3. Anh’s Secret Awareness In the book, Olive’s best friend Anh does not know about the fake relationship. But in the movie, Anh realizes early on that the dating is fake and lets it run its course, believing Olive and Adam will fall for each other. That shift alters Anh’s role from an observer to someone who shapes the central relationship.

4. Who Ends the Relationship The breakup in the third act is a major emotional turning point. In the book, Olive pulls away after being harassed by Tom Benton and ultimately ends things because she fears the consequences for Adam. In contrast, in the film, Adam is the one who ends the fake relationship — he believes it’s necessary for Olive’s career — which shifts the weight of guilt and resolution between them.

5. Tom Benton’s Harassment & How It’s Exposed The power abuse by Tom Benton is central in both versions but handled differently. The book has Olive secretly record his harassment/ultimatum then later uses that to confront him publicly. The movie removes that recording twist; instead, the exposure happens through other characters (notably Anh), changing how Olive’s agency and power dynamics play out.

6. Different Ending / Epilogue The book ends with a one-year epilogue: Olive and Adam recreate their first kiss and show how their relationship is progressing. The movie extends the timeline to two years, and adds substantial career development—highlighting Olive’s rise, including a role as a Stanford professor alongside Anh and Adam.
